Hi - I noticed that the listing page sliders display the full sized image as it was uploaded and use CSS to constrain the image dimensions. Wouldn't it be better to resize the slider images as they are uploaded, and then use the processed image sizes in the slider? Seems like this would be better and more efficient than displaying the images that are uploaded, which could get into the hundreds of k's.
Hello, Currently theme don't have any image editor or re-sizer. You can add a note (Like: "Please upload image of dimension nearly '800 x 600' px") for user in the image upload description field. And also you can use "WP Image Size Limit" plugin. Download it from the link given below. http://wordpress.org/plugins/wp-image-size-limit/
